Li3BrO
Li3BrO is a metastable antiperovskite material being studied as a potential solid-state electrolyte for lithium-ion battery technology.
About Li3BrO
Li3BrO is an inorganic compound belonging to the antiperovskite lithium conductor class. Characterized by its wide-band-gap insulating electronic nature, this material is of significant interest in the development of advanced solid-state electrolytes for next-generation energy storage systems.
Although it is classified as a metastable phase, Li3BrO has attracted attention due to its structural configuration. It is part of a growing family of lithium-rich materials being investigated for their potential to facilitate rapid ion transport, which is essential for improving the safety and efficiency of lithium-based batteries.
Key Properties
Cross-validated computational properties for Li3BrO, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
